Stock Quarter Mile
Reply #1 –
15.5? That's pretty good...you're right about all of that. Wow. Any idea what rear end ratio it has?
I have a G-Tech Pro (the FIRST one they ever made in like 1999) and it repeatably gave me 9.4 seconds as a 0-60 for my 1987 20th Anniversary Cougar. Stock 5.0 150 horserpower, car itself, 1/4 tank of gas, me not sitting in it, weighs 3550 lbs.
I think it would be at LEAST a 17 second 1/4 mile, maybe even 18 or 19 depending on options. I think sheetmetal-wise, the Tbirds have a slight weight advantage, and power seat tracks EACH are about 50 lbs. So ranging from an ultra-stripped down four-eye car to a fully loaded 87/88, 5.0/AOD/2.73 rear held constant let's say (that's what I *had* at that run), you could see some significant variation in speediness...
I know Mark VII LSC's could have a 3.27 gear optionally, the LSC anyway with the H.O. would have gotten the 8.8 axle. Not sure if anything higher was available. Next one up would be 3.55 but I feel like that wouldn't be a factory car gearset. Ranger? Maybe.
